Abstract

  Whether a WLAN terminal is available on one accessible WLAN access point or another accessible WLAN access point, at least some of the SSIDs on the preferred SSID list provided for that WLAN terminal When making a decision, each probe message sends multiple probe messages, each indicating a single SSID, to an accessible WLAN access point, but each indicator in the list above assigns an SSID on the list to the WLAN. A method of sending probe messages for that SSID only when the terminal indicates that it is looking.

Description

  The present invention relates to the field of wireless local area network services. More particularly, the present invention relates to a WLAN terminal that detects an SSID.

  A service set identifier (SSID) is a unique identifier of 32 characters that is attached to the header of a packet transmitted over a wireless local area network (WLAN), and the mobile device goes to the basic service set (BSS). Acts as a password when attempting to connect. Each set of wireless devices that are in direct communication with each other is called a BSS. Several BSSs can be combined to form one logical WLAN segment. We call it an extended service set (ESS). The SSID is simply an alphanumeric name of 1 to 32 bytes given to the ESS.

  Thus, the SSID distinguishes one WLAN from another. Therefore, all access points (hardware devices or computer software that function as communication hubs for wireless device users to connect to wired WLAN) and all devices attempting to connect to a given WLAN You must use the same SSID as the SSID for your WLAN. In general, a device is not allowed to join a BSS unless the device can provide its BSS-specific SSID. The SSID is also called a network name. This is because the SSID is a name that actually identifies the (wireless local area) network.

  A WLAN includes one or more access points and two or more stations. For example, a department's WLAN (ESS) in a company can have several access points and dozens of stations, all of which use the same SSID. Another division of the company in the same building may use its own WLAN consisting of multiple access points and stations using different SSIDs. The purpose of the SSID is to help the station in the first department find and connect to the WLAN access point in that first department, and ignore the access points belonging to the second department.

  Each access point notifies its presence several times per second by sending a beacon frame containing the ESS name or SSID. A station can discover an access point for an ESS by passively listening to a beacon. Alternatively, the station can send a probe frame to actively detect an access point with the SSID of that ESS. When the station finds an access point with a nearly desired name, it can send an associate request frame containing the desired SSID. The access point sends back an associate response frame that also contains the SSID.

  The wireless device thus establishes and maintains a connection using the SSID. As part of the association process, the wireless network interface card (NIC) for a station with a WLAN must have the same SSID as the access point (s) for that WLAN. Traditional access points only support a single SSID, but now several companies offer enterprise-level access points that support multiple SSIDs. Multiple SSIDs allow users to access different networks through a single access point. Network managers can assign different policies and functions for each SSID. This increases the flexibility and efficiency of the network infrastructure. Using multiple SSIDs means greater flexibility when developing a shared WLAN infrastructure. A WLAN does not only support one type of application (perhaps an application that requires significant authentication and encryption), but can also maintain other types of applications.

  To indicate whether the WLAN service is available, the WLAN access point periodically transmits a broadcast beacon message containing the access point's SSID as described above. One access point of the WLAN can broadcast one or more SSIDs in separate beacon messages.

  In addition to broadcast SSIDs, WLAN access points can also support other SSIDs not notified by beacon messages. There are several reasons why a WLAN access point may not broadcast several SSIDs simultaneously. First, most access points in a WLAN support multiple SSIDs, but usually can only transmit beacon messages for only one of them. Second, in the case of a private (eg, corporate or residential) WLAN, when a beacon message is sent, it may be easier for an outside person to detect the presence of the WLAN network.

  The only way for a mobile WLAN terminal to find these additional SSIDs is to send a broadcast probe message and ask if a nearby WLAN access point supports a particular SSID. is there. When a WLAN access point that supports the SSID receives a probe message, the access point sends back a probe response message.

  Thus, the WLAN terminal passively receives broadcast transmission information (beacon message) to find the broadcast SSID from all available WLAN access points. However, this does not guarantee that all the SSIDs available to the WLAN terminal are known.

  For a WLAN terminal to send a probe message, it needs to know the SSID value that the WLAN terminal is interested in. Such SSID values are included in what is called the preferred SSID list in the WLAN terminal. The preferred SSID list can be quite long, so sending a probe message for each SSID on the list can not only affect the power allowed for the WLAN terminal, but also the WLAN It may also affect the time and radio capacity of the terminal. It is therefore desirable to avoid sending a probe message for each SSID on the preferred SSID list.

  Since the priority SSID list is related to the 3GPP-WLAN interworking terminal, the prior art cannot cope with the above situation. Current WLAN solutions (for laptops) expect users to select one of the SSIDs sent in the beacon message themselves or type in the SSID to look for Yes. Therefore, a situation in which the WLAN terminal has to detect multiple SSIDs does not occur.

  In view of the above situation, in the first aspect of the present invention, at least some service set identifiers in a priority list of service set identifiers (SSIDs) provided in a wireless local area network (WLAN) terminal A method used by a wireless local area network terminal to determine whether any of these are available at a wireless local area network access point A method is provided that includes transmitting a plurality of probe messages, each probe message indicating a service set identifier, for reception by a wireless local area network access point. Here, the method includes a probe message for one service set identifier in a priority list of service set identifiers, wherein a list associated with the one service set identifier is a wireless local area network. Including transmitting only when the terminal indicates to detect the one service set identifier.

  According to a first aspect of the invention, the list may include an indicator indicating that the wireless local area network terminal detects one service set identifier.

  According to the first aspect of the present invention, the indicator may be stored separately from the list, and the indicator has a specific association with the service set identifier in the list.

  According to the first aspect of the present invention, the indicator may be stored in the memory card of the wireless local area network terminal.

  Also according to the first aspect of the invention, the indicator may be stored in a subscriber identity module used with a wireless local area network terminal.

  According to the second aspect of the present invention, there is provided an apparatus used by a WLAN terminal when performing the method according to the first aspect of the present invention.

  The above objects, features and advantages of the present invention, as well as other objects, features and advantages of the present invention will become apparent from the following detailed description with reference to the accompanying drawings.

  The present invention relates to a wireless local area network (WLAN) terminal, wherein any of at least some SSIDs on a preferred list of service set identifiers (SSIDs) provided in the WLAN terminal are: Helps determine if it is available on a WLAN access point. According to the present invention, a preferred SSID list is provided. Each SSID on this list has a flag or other indicator that indicates whether to look for that SSID, or at least that list determines whether to look for a given SSID on that list Some basis for is included. The WLAN terminal can skip detecting the SSID that is expected to be broadcast in the beacon message because the flag or probe indicator indicates whether to look for the SSID on the list . The flags (and preferred SSID list) can be entered or pre-programmed by the user, operator, manufacturer, or other service manager, or downloaded to the WLAN terminal through the wireless interface.

  In one embodiment of the invention, the preferred SSID list includes flags for the home operator's SSID and only a few other SSIDs (the most important ones), which the user misses. Do not. Alternatively, there may be several tens of flags.

  In FIG. 1, in addition to the WLAN terminal 11 and the priority SSID list 12 associated therewith, three different WLAN access points AP1, AP2, AP3 are also shown. The first access point AP1 supports the SSID indicated as SSID1 (transmitted in the beacon message) and SSID1a (not transmitted in the beacon message). As shown in the preferred SSID list 12, the most preferred SSID of the WLAN terminal is SSID1a, but the WLAN terminal probes to discover that it can be used by the first access point.・ You must send a message. According to the present invention, an indicator is provided that indicates that only SSID 1a should be searched and that SSID 2 transmitted in the beacon message is not searched.

  Referring to FIG. 2, a typical configuration of the priority SSID list 12 of the WLAN terminal 11 is shown. The priority SSID list 12 is stored in this configuration in a non-volatile memory structure included in the WLAN terminal. The SSID list can also be stored in a subscriber identification module used in the WLAN terminal. Flags or probe indicators associated with individual SSIDs on the SSID preference list can be stored with this list, or stored separately from this list (for example, a relational database type database in a separate table). be able to. As shown in FIG. 2, the WLAN terminal of the present invention also generally includes a probe module that detects an SSID on the priority SSID list, and the probe module uses a transceiver (TRX) to transmit a signal related to this search. Send and receive.

  The flag or probe indicator can be provided at the same time as the SSID priority list as part of the SSID priority list, or can be provided later separately from the SSID priority list. For example, the SSID priority list can be provided with placeholders for flags or probe indicator values. This value can be set later, for example by an operator or software distributor, or even a user. In order to prevent the WLAN terminal from detecting the SSID contained in the beacon message, it is possible to know which SSID was broadcast by monitoring the beacon and set the flag or probe indicator. Thus, it is even possible for the flag or probe indicator to be set automatically by the WLAN terminal.

  Whether the probe signal is transmitted from a WLAN terminal to a specific individual WLAN access point or broadcasted to all accessible WLAN access points is not the subject of the present invention.

  It will be understood that the above arrangement is merely illustrative of the application of the principles of the present invention. Since many changes and other configurations may be devised by those skilled in the art without departing from the scope of the invention, the appended claims are intended to cover such changes and configurations.

FIG. 2 is a schematic diagram of a WLAN terminal, which is a schematic diagram of a WLAN terminal that performs detection to determine which SSID is supported by a WLAN access point that can access the WLAN terminal. FIG. 2 is a block diagram of a WLAN terminal, showing elements related to the present invention, that is, a memory structure in which a priority SSID list of this WLAN terminal is provided, and for this SSID on the list, the SSID should be searched for It is a block diagram which shows that the indicator or flag which shows whether it is included is included.
